Intel’s tenth generation octa-core hyperthreaded i7-10700K is one of the fastest high-end desktop CPUs ever made. A simple overclock yields all 16 threads running at a staggering 5.1 GHz. Gaming and desktop performance is second only to the flagship i9-10900K. Although a new (Z490) LGA1200 motherboard is required, it will remain compatible with Rocket Lake CPUs which are due later this year. The 10700K’s $400 USD price tag puts it in a similar price band to AMD’s 12-core hyperthreaded Ryzen 9 3900X, however, the 10700K’s faster cores combined with its lower memory latency, yield a 12% effective speed advantage over the 3900X. Intra-generationally comparing the 10700K and 10600K shows that the 10600K offers almost identical gaming performance for 34% less money. [Jun '20 CPUPro]

The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]
